"Only when you do close observation can you see them. Sunspots are like magnetic fields, when iron fillings are put near a simple bar magnet on earth, the fillings show a pattern the same thing happens to the sun, this pattern is called a sunspot."
"Sunspots are like "magnetic scabs" of gas unable to be recirculated to lower, hotter levels."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
